Artists doing fan art are infringing copyright, yes. If the fan art meets the fair use criteria then they are not Infringing.
Companies usually overlook the infringement from fan artists because it’s free advertising and the public backlash is not worth going after lone artists. They usually will go after fan art of people that profit off it.
But it’s golden and has a convicted felon’s name on it. That should make up for the rest of the value right?
